Most of them are listed with a buyout of 2 flezz… a good flezzsink makes it easy to squander large sums of flezz with little or no gain, this makes it hard for you to squander a small amount of flezz, and even if you had the patience to go through with it you could get half your money back from the ppwn shoppe.

600 pages, 12 per page, 2 flezz each = 14400 flezz, the ones without a buyout might go for more but without some bidding wars opening up its not going to sink a lot of flezz, and bidding wars happen over marbles without requiring 600 pages of them.

So basically he’s just super-cool for having, and listing, that many marbles, not a flezzsink-creating mastermind.
